01/The problem

Apartment buildings have terrible software.

A $1.4 trillion global market still run on email, paper notices, and group chats. Residents miss things. Managers burn out. Owners can’t see where the money goes.

Core

Directory.

Every resident, owner, committee member. Searchable. Role-permissioned.

05/Operations

Running the building, on rails.

Tasks, messages, marketplace, documents, voting — every operational surface a building needs, all in one app. No spreadsheets, no separate chat groups, no paper.

Tasks

Every issue, tracked end-to-end.

Residents report. Managers assign. Vendors update. Owners see the trail. From first ticket to closed, the whole building stays informed.

Messages

Direct line. No new app.

1-to-1 and group chat — residents to managers, committee to owners.

Marketplace

Building-only buy & sell.

Furniture, parking spots, lost & found — neighbours only, no marketplace creeps.

Documents

By-laws, minutes, contracts — one library.

Searchable, permissioned, version-tracked. Owners get owner docs. Residents get resident docs. No more email chains.

Voting

Decisions counted. No paper.

Owners vote on motions in 30 seconds from their phone. Quorum auto-tracked. Results logged.

06/Built for everyone

One platform. Every role.

Residents, owners, committee members, building managers — and strata firms next. Five roles, one quiet surface.
